[0002] The automotive roof crossbeam, also known as the side roof crossbeam, is a crucial component of the vehicle's structure. Typically a sheet metal stamped part, it consists of roof side beams, the roof crossbeam itself, and connecting plates forming a closed cavity. It provides structural support and reinforcement for the vehicle's roof structure, thus its structural strength and rigidity significantly impact the vehicle's resistance to deformation. However, because the connection area between the roof crossbeam and the side wall needs to avoid welding equipment, the central section often requires large openings such as process holes or clearance holes, resulting in weaker structural strength in this area. Improving this by increasing the part's thickness or material grade would introduce new problems such as increased part cost and weight. Summary of the Invention
